An edge device includes a first antenna array and a sensor that senses a surrounding area of the edge device. The edge device further includes control circuitry that detects a first user in the surrounding area of the edge device sensed by the sensor. The control circuitry tracks the detected first user in the surrounding area of the edge device based on the sensor and control the first antenna array to direct a first beam of radio frequency (RF) signal having a signal strength greater than a first threshold in a first direction of the first user being tracked based on the sensor for high-performance communication.

In a particular implementation, a method includes receiving, at a first base station from a second base station via a backhaul communication, a scheduling message indicating one or more beams of the second base station that are scheduled for use in upcoming transmissions. The second base station is a neighboring base station of the first base station.

Certain example embodiments provide systems, methods, apparatuses, and computer program products for enhanced traffic co-existence with multi-panel user equipment (UE). For example, certain embodiments may avoid excess dropping and/or cancellation. Taking inter-UE uplink (UL) prioritization as one example, whenever a network node has to accommodate higher-priority traffic on resources overlapping with ongoing and/or incoming lower-priority transmissions, certain embodiments may instruct a UE to transmit on spare antenna panel(s).

The present disclosure relates to a communication method and apparatus, a terminal, and a storage medium. A terminal device sends first indication information to a network device, the first indication information being used to indicate a first transmitted precoding matrix indicator (TPMI) group, and the first TPMI group being a TPMI group in a TPMI group set; and then, receives a first TPMI indicated by the network device. By using the described method, the uplink coverage capabilities of a terminal device and the uplink transmission performance of a terminal device can be increased.

A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.
